Abstract :
Enhanced uplink technology is being standardized in release-6 of 3GPP W-CDMA specifications with the completion date of 2nd quarter of 2005. Advanced features being introduced include adaptive modulation and coding, hybrid ARQ, fast rate control or scheduling by the base station, higher peak rates (5.76 Mbps) and support of 2 ms TTI. These techniques reduce overall delay and increase throughput significantly compared to earlier releases of 3GPP W-CDMA (release-99/4/5). As a result, enhanced uplink significantly improves the user mobile experience and enable new services and applications. In this paper, the scheduling and resource allocation aspects of enhanced uplink are discussed with accompanying analysis and system simulation results. These results show that enhanced uplink improves sector and user throughput by approximately 50-80% compared to earlier 3GPP W-CDMA releases
